| 3500 is normal...20kph difference is alot get someone to check your speed against...cause its still got 13s on it the speedo shouldnt be out unless you have changed the gear in the speedo drive in the 'box... |

| At 100kph you should be doing about 4000rpm. |

| With standard gear and diff ratios, in a 4 speed manual gear box 3900rpm is 100khm, 3334rpm is 100kmh in 5th. |
